What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.
y = 2⁽ᵃˣ⁺ᵇ)
x = - 1 y = 2 = 2¹
=> ax + b = 1 => -a + b = 1
=> b -a = 1
x = 0 y = 8 = 2³
=> ax + b = 3 => 0 + b = 3
=> b = 3
b -a = 1
=> 3 - a = 1
=> a = 2
checking for others
x = 1 y = 32 = 2⁵
ax + b = 2(1) + 3 = 5
x = 2 y = 128 = 2⁷
ax + b = 2(2) + 3 = 7
The equation is y = [tex]2^{2x+3}[/tex]
Hence the equation of the function is found to be y = [tex]2^{2x+3}[/tex].

What is the slope of the line shown below? (6, 2); (- 2, - 3); 8/5; 5/8; - B/5 D. - 5/8
The slope of the line shown below is -5/8.
What is slope?Slope is the measure of the steepness or incline of a line or surface. It is calculated by measuring the ratio of the vertical change over the horizontal change between two points. It is a mathematical concept used in algebra, geometry, and calculus to measure the rate of change of a function or line. Slope is also used to identify the direction of a line or surface. It is represented by the variable ‘m’ and is calculated by dividing the vertical change by the horizontal change between any two points on a line or surface.
This can be determined by using the formula for slope, which is (y2 - y1)/(x2 - x1). In this equation,
(y2 - y1) = -3 - 2 = -5 and (x2 - x1) = -2 - 6 = -8. Thus, the slope of the line is -5/8.

In this activity, you are investigating the financial viability of the martingale betting strategy that was introduced in class.
Recall how a martingale works. You place a bet on any "even money" event (that is, a wager where winning means gaining the money bet). If you win, you stop — you have won money. If you lose, you keep doubling the bet until you win, and then stop. Your winnings will cover the previous losses. Unfortunately, a long losing streak means that you run out of money and can no longer bet – hence losing a lot.
Balph Snerdwell has $31 in his wallet. He is going to be betting on red or black, at the roulette table. Recall that, in an American casino, there are 38 numbers — 18 red and 18 black (plus 0 and 00). So Balph has an 18/38 probability of winning, each time he bets.
a) Balph plays a martingale — doubling his bet after each loss. What’s the maximum number of times he can lose? Why?
b) Recall that Balph might win a dollar from playing a martingale … or he might lose all $31 in his wallet. What’s the probability that he wins a dollar? That he loses everything?
c) And so, what is the expected value of Balph’s net winnings, from one martingale?
d) Sometimes Balph will bet only one dollar. But sometimes he will bet three dollars (if he loses, then wins). Or seven dollars (lose, lose, win). Or some other amount. What are the possible values for total amount wagered? Their probabilities? Therefore, what is the expected value of the numbers of dollars wagered?
e) In Part D you found how much money Balph won, on average. In Part E, you found how much money Balph bet, on average. How much did Balph win, per dollar bet? (Does this number look familiar?)
The answers are:
b) 0.9596, 0.0404
c) expected value of dollars won = -$0.29236
d) expected value of dollars wagered = $5.55475
Can someone please break it down and explain how they got the answers
Answer:
a) Balph can lose a maximum of 6 times in a row before running out of money and not being able to place any more bets. This is because if he loses 6 times in a row, he would have to bet $64 (1+2+4+8+16+32) which is more than the $31 he has in his wallet.
b) The probability that Balph wins a dollar is 0.9596 and the probability that he loses everything is 0.0404. These probabilities are calculated by assuming a 18/38 probability of winning each bet and using the martingale betting strategy.
c) The expected value of Balph's net winnings from one martingale is -$0.29236. This means that on average, Balph can expect to lose $0.29236 each time he plays the martingale betting strategy.
d) The possible values for the total amount wagered are $1, $3, $7, $15, $31, and $64. These values correspond to the amount wagered after losing 0, 1, 2, 3, 4 and 5 times in a row. The probability of each value depends on the probability of losing that many times in a row, calculated using the 18/38 probability of winning each bet. The expected value of the number of dollars wagered is $5.55475.
e) The amount Balph wins per dollar bet is -0.0527. This number is calculated by dividing the expected value of Balph's net winnings by the expected value of the number of dollars wagered. This number is less than zero, indicating that on average, Balph will lose money for every dollar he bets.

what is a linear function?
A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by;
y = f(x) = px + q
It has one independent and one dependent variable. The independent variable is x and the dependent one is y. P is the constant term or the y-intercept and is also the value of the dependent variable. When x = 0, q is the coefficient of the independent variable known as slope which gives the rate of change of the dependent variable.
Now
Initial value = $2.25 in 1994
cost in 2016 = $3.99
Therefore
3.99=2.25+2.25*r*22/100
r=0.079
where r=rate
then
Average cost=initial value+0.079t
Hence
A=$(2.25+0.079t)
where t=time (given year - 1994)
cost in 2020=$(2.25+0.079*26)
cost in 2020=$4.3
Now for A=$5
5=2.25+0.079t
t=35years
Hence Average cost will be $5 in year 2029.

The function f is defined on the closed interval [-5,4]. The graph of f consists of three line segments and is above in the figure above. Let g be the function defined by g(x) = integral_2_-3 f(t) dt. a. Find g(3) b. On what open intervals contained in -5 lessthan x lessthan 4 is the graph of g both increasing and concave down? c. The function h is defined by h(x) = g(x)/5x. Find h'(3). d. The function p it defined by p(x) = f(x^2 - x). Find the slope of the line tangent to the graph of p at the point where x = -1.
a. g(3) = -2
b. g is increasing and concave down on the intervals (-3 <= x < 2) and (2 <= x <= 4).
c. h'(3) = 0
d. The slope of the tangent line to the graph of p at x = -1 is -3.
a. The function g is defined as the definite integral of f(t) with respect to t from -3 to 2. Therefore, g(3) = integral_2^3 f(t) dt. From the graph, we can see that:
f(t) = 2 for -5 <= t < -3f(t) = -t for -3 <= t < 2f(t) = 2t - 8 for 2 <= t <= 4.Therefore, g(3) = integral_2^3 (-t) dt + integral_2^3 (2t - 8) dt
= -1/2(3^2 - 2^2) + 1/2(3^2 - 2^2 - 8(3 - 2)) = -5/2 + 1/2 = -2.
b. The graph of g is increasing and concave down when the graph of f is concave down and when the definite integral of f is increasing. From the graph of f, we can see that f is concave down on the intervals (-5 <= t < -3) and (2 <= t <= 4). Therefore, g is increasing and concave down on the intervals (-3 <= x < 2) and (2 <= x <= 4).
c. The function h is defined by h(x) = g(x)/5x. To find h'(3), we need to use the quotient rule for derivatives. h'(x) = (5xg'(x) - g(x)5)/5x^2.
Since g(x) = integral_2_-3 f(t) dt, it is not a function of x, so g'(x) = 0. Therefore, h'(3) = (530 - 05)/53^2 = 0.
d. The function p is defined by p(x) = f(x^2 - x). To find the slope of the line tangent to the graph of p at the point where x = -1, we need to find the derivative of p at -1. Using chain rule: p'(x) = f'(x^2-x)(2x-1) so p'(-1) = f'(-1) * (2(-1)-1) = (2(-1) -1) = -3.
Therefore, the slope of the tangent line to the graph of p at x = -1 is -3.

6p + 4d = 65
Alonso went into the same movie theater and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50. This will be:
9p + 8d = 107.50
Equating the equation
6p + 4d = 65 ..... i
9p + 8d = 107.50 ..... ii
Multiply equation i by 8
Multiply equation ii by 4
48p + 32d = 520
36p + 32d = 430
12p = 90
Divide
p = 90/12
= 7.5
6p + 4d = 65 .
6(7.5) + 4d = 65
4d = 65 - 45
4d = 20
d = 20/4 = 5

14. Damian is building a display case to hold
75 model cars. The case will have fewer
than 10 shelves, and each shelf will hold
no more than 15 cars. If Damian wants
each shelf to have the same number of
cars, how many shelves should he put in
the display case?
Damian should put 5 shelves in the display case to hold 75 model cars and ensure that each shelf has the same number of cars.
What is the unit value?
Unit value is a measure of the price of a single unit of a good or service. It is calculated by dividing the total cost of the good or service by the number of units purchased. It is also known as unit cost.
To determine how many shelves Damian should put in the display case, we can use the following steps:
Divide the total number of cars by the maximum number of cars per shelf. In this case, 75 model cars / 15 cars per shelf = 5
If the number of shelves is not a whole number, round up to the next whole number. In this case, 5 shelves is already a whole number, so we don't need to round up.
Check that the number of shelves is less than 10. In this case, 5 shelves are less than 10 shelves.
Hence, Damian should put 5 shelves in the display case to hold 75 model cars and ensure that each shelf has the same number of cars.

Which of the following is an example of a variable measured at the nominal level of measurement?
A. Location in which respondent was born
B. Religiosity measured as not religious, somewhat religious, and very religious
C. Time in seconds in which a subject completes a given task D. Number of respondents' first cousins
E. Level of education in years completed
Religion is an example of a variable measured at the nominal level of measurement. Thus, option B is correct.
Nominal values are those that cannot be quantified by numbers, such as when calculating age or tallying academic accomplishments. As opposed to the ordinal, interval, or ratio measurements, it is the level of measurement representing a variable that just has distinct properties.
Since the 'characteristic' or 'identity' we are interested in is just named, the nominal level of measurement is the least accurate and illuminating. In nominal variables, the numerical values just "label" the attribute in a distinctive way. The numerical value is just a label in this instance.
